Completed 시 per-instance 북키핑 정리는 불필요 — 자연완료는 유저가 원한
목표값에 도달한 상태라 남은 참조가 부작용 없고, Value가 lerp 가능한
프리미티브라 메모리 문제도 없어 별도 정리 장치는 오버엔지니어링. 이걸로
tween-plan.md에 남은 열린 질문이 없어져 research/에서 base/로 승격,
라이브 크로스레퍼런스 전부 갱신.

Sketch Sum/Not/Product-style :Compute/:Apply sugar (research/operator-sugar-plan.md,
implementation deferred). Reusable curried combinators (Sum, Animate) must
go through :Apply, not :Compute — quad rejected implicit auto-tracking, so
a factory's closed-over deps only register if the factory re-declares them
via self:Compute(...) internally; plugging a pre-built factory straight
into :Compute silently drops reactivity. Flip Animate's call site
accordingly in tween-plan.md, add the convention to bind-system-plan.md's
:Apply section, and fix a stale two-arg Animate signature comment in
architecture.md.
